WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK,
OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer at the address or telephone number listed below
the warranty.
2. Before servicing or cleaning unit, switch power off at
service panel and lock the service disconnecting means
to prevent power from being switched on accidentally.
When the service disconnecting means cannot be locked,
securely fasten a prominent warning device, such as a
tag, to the service panel.
3. Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable
codes and standards, including fire-rated construction
codes and standards.
4. Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of fueling
equipment to prevent backdrafting. Follow the heating
equipment manufacturer’s guideline and safety standards such as those published by the National Fire
WARNING
Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. This unit must be grounded.
CAUTION
1. For general ventilating use only. Do not use to exhaust
hazardous or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust,
etc. off power unit.
3. If ventilator is installed in an unconditioned space
(such as an attic): Surround the ventilator with thermal
insulation - to minimize possible condensation.
4. Please read specification label on product for further
information and requirements.
PLAN THE INSTALLATION
Adequate ventilation requires that both intermittent and
continuous contamination be controlled.
Intermittent ventilation must be provided in the bathroom
and kitchen. The bathroom requires 8 air changes per hour.
(Multiply bathroom sq. footage by 1.1 for proper fan sizing).
The kitchen requires a minimum of 150 CFM capacity (71
l/s) when a ducted range hood is used. If a kitchen fan is
used, determine fan capacity by multiplying the room's sq.
footage by 2. All are run intermittently to control pollution at
the source.
Continuous ventilation, while the house is occupied, provides the flow of fresh air for good indoor air quality.
This ventilator is intended for continuous operation, supplying fresh air to the entire house.

VENTILATOR
The ventilator exhausts stale air. There are normally sufficient natural intake openings into a dwelling to admit fresh
outside air to be drawn in to replace the stale air. For better
control, fresh air inlets may be used.
The ventilator should be centrally located to keep ductwork
as short as possible. Locations for the ventilator include:
joists in an attic space or the basement, or a wall away from
the living areas.
EXHAUST
DIFFUSERS
(Available separately)
Exhaust diffusers regulate
the flow of fresh air drawn
through the house.
Exhaust diffusers should
be mounted in the ceilings or high on the wall.
For best performance, exhaust diffusers should be
mounted in a central location. An exhaust diffuser
should not be installed
near a cooking area. (see
figure)

For best control of fresh air in a room, install a fresh air inlet.
The number of inlet vents depends on the floor plan.
Consider the rooms/areas through which fresh air should
flow toward the exhaust diffuser(s).
Vents should be located in outside walls, preferably near
the ceiling and approximately the same distance from a
diffuser. Vents should be separated from diffusers far
enough to allow fresh air to mix with room air before being
exhausted.

2. To minimize condensation inside of ductwork in the attic, cover ductwork with additional insulation. Also, avoid
forming condensation traps in the ductwork runs.
3. Seal ductwork to ventilator and roof or wall cap with duct
tape or clamp (available separately).

If some ventilator inlets will not be used:
Place the inlet
cover(s) (provided) over the unused inlet(s) and tape
them in place.
